E4-02
= f - (n × p) / 120
•
f: Motor rated frequency (Hz)
•
n: Rated motor speed (min
-1
(r/min))
•
p: Number of motor poles

E4-03: Motor 2 Rated No-Load Current
No.

Name
Description
Default

E4-03
(0323)
Motor 2 Rated No-Load
Current
Sets the no-load current for motor 2 in amps when operating at the rated frequency and the no-load
voltage.
Determined by o2-04, C6-01
(Less than 0 - E4-01)
Note:
When the drive model changes, the display units for this parameter also change.
•
0.01 A: 2004 to 2042, 4002 to 4023
•
0.1 A: 2056 to 2415, 4031 to 4720
You can also manually enter the motor no-load current shown on the motor test report to
E4-03
. Contact the motor
manufacturer to receive a copy of the motor test report.
Note:
The default setting of the no-load current is for a 4-pole motor recommended by Yaskawa.

Motor 2 Motor Poles
Sets the number of poles for motor 2.

Auto-Tuning automatically sets
E4-04
to the value input for [Number of Motor Poles].

E4-05: Motor 2 Line-to-Line Resistance
No.
(Hex.)
Name
Description
Default
(Range)
E4-05
(0325)
Motor 2 Line-to-Line
Resistance
Sets the line-to-line resistance for the motor 2 stator windings.
Determined by o2-04, C6-01
(0.000 - 65.000 Ω)
Note:
This value is the line-to-line resistance for motor 2. Do not set this parameter with the per-phase resistance.
The drive automatically calculates this value when Auto-Tuning completes successfully. If you cannot do Auto-
Tuning, get the test report from the motor manufacturer. To calculate the motor line-to-line resistance, use the
information shown on the motor nameplate with one of these formulas:
•
E-type insulation: the resistance value (Ω) shown on the test report at 75 °C × 0.92
•
B-type insulation: the resistance value (Ω) shown on the test report at 75 °C × 0.92
•
F-type insulation: the resistance value (Ω) shown on the test report at 115 °C × 0.87
■
E4-06: Motor 2 Leakage Inductance
No.
(Hex.)
Name
Description
Default
(Range)
E4-06
(0326)
Motor 2 Leakage Inductance
Sets the voltage drop from motor 2 leakage inductance as a percentage of Motor Rated Voltage when
motor 2 operates at the rated frequency and rated current.
Determined by o2-04, C6-01
(0.0 - 60.0%)
The drive sets this parameter during Rotational Auto-Tuning and Stationary Auto-Tuning.
Note:
You cannot usually find the quantity of voltage drop on the motor nameplate. If you do not know the value of the motor 2 leakage
inductance, get the test report from the motor manufacturer.
